Bulk powerFull and hair color???

I'm 39, and have had slowly increasing grey hair since my mid 20s. Its not too bad on my head, they are mixed in (and its better than loosing the hair), but in my facial hair its quite noticeable. Enough so that I dont grow a goatee anymore, since there are a couple of large patches of grey. Well this week I shaved tues morning, then not till today since i happen to not have to worry about it for work and it seemed that before I shaved it there was way less grey hair than I recall, and more dark brown. Has any of the other slightly older board members noticed anything like this?

Now this would be interesting, if true. I suspect it's coincidence, but.... I'm 37 and getting a grey hair appear now and then, and I was thinking of giving powerfull a go in the nearish future. This would be a GREAT side effect if it was dinkum!
